Looks like weed is indeed the wonder plant that Rastafaris claim it to be. Research carried out on older mice has shown that THC in cannabis improved their learning abilities and memory. After being dosed with THC, older mice displayed similar powers of recollection as younger rodents.
The results of the study have been published in Nature Medicine and the project has been hailed as a prospective breakthrough in understanding how ageing affects the brain. A new study with around a 100 humans is now being planned in order to better understand the effects of THC on the cognitive abilities of those in the age group 60-70 years. The endocannabinoid system of the brain begins to slow down as we age.
This system, which responds to cannabinoids, is associated with memory and moods. Scientists conjecture that if doses of THC can work for mice long in the tooth, then it may hold promise for humans, and may help find cures for dementia.
However, when young mice were dosed with THC, their performances in memory-related tasks faltered. This, researchers aver, is because the THC actually sends the system into hyperdrive.
Of course, this does not mean that all those above 60 should start smoking pot or that you’ll seen be able to get marijuana medications over the counter at pharmacies.
